I will go so far as to say that only those who are willing to take on such responsibility, to make the appropriate commitment to learn and train and make a conscious decision that they won't pull the trigger until it is absolutely necessary, but that when it is necessary, they will not hesitate. This would exclude an awful lot of people in my opinion, especially a lot of folks who think they need a gun for something, but never really take it that seriously. I don't think anyone, including military personnel, should be required to own or possess a firearm. In fact, giving guns to people who shouldn't have them is worse than not arming them at all.
